To all whom it may concern:

Be it known that l Frorn E. Emerita-n a citizen of the United States, residing at Chicago, Cook county, Illinois, have invented certain new and useful Improvements in Dump-VVagons, of which the following is a specification.

The present invention has reference to certain improvements in dump wagons.

It has particular reference to improvements in a dump wagon. so-constructed that the coal; sand, rock, or other load can be discharged from the rear end of the hopper directly to the desired point of delivery.

he dump wagon to which the present invention relates is provided w. n a hopper portion and with a discharge or delivery portion, the latter being so constructed in some instances that the load can be discharged to a chute at either side of the hopper, or straight down therefrom, as desired.

One of the objects of the invention is to so relate the hopper and discharge portions that the load can be delivered in either of the manners, or at either of the points enumerated above.

Another feature of the invention has reference to the construction of the discharge portion itself, whereby the discharge of the load can be most easily controlled. Also to so construct this portion of the wagon that the delivery of the load in either of tee manners enumerated can be effected under the control of theoperator with. a very small number of movable parts related to each other in a very simple manner.

Another feature of the invention has reference to the relative mountings of the hopper and discharge portions so that the entire load can be regularly and continuously plied thereto hopper and discharge portionsembodying the features of the present in- Vcntion; Fig. 2 is a rear view of the wagon shown in Fig.1. In this figure the left hand chute has been released so as to effect a discharge of the load at the left hand side; Fig. 3 is a section taken on the line 33 of Fig. 1 looking in the direction of the arrows, being a section corresponding to the View shown in Fig.2; Fig. 4 is a view simi lar to Fig. 3. with the exception that the chutes have been released in such a manner as to discharge the load straightdown instead of to one side. Fig. 5'is a face view looking at the central removable plate of the discharge portion; Fig. 6 is a detail of one end of one of the side plates; Fig. 7 is a detail view of the interlocking connection between the central plate shown in Fig. 5, and one of the side plates with which the same cooperates, the central plate in Fig. 7 standing in fully released position; Fig. 8 is a detail *iew corresponding to that of Fig. 7 with the exception that the plates are standing in the position which they normally occupy; and Fig. 9 is a view correspending to Figs. 7 and 8 with the exception that the central plate is standing in the position which it occupies for the discharge of the load to one side.

In the several figures the wagon frame is designated by the numeral 10. At its rear end it carries the discharge portion 11, and in its central portion it carries the hopper 12. This hopper is pivoted at its lower rear corners 13 so that its front end may be raised upward as shown by the dotted lines in 1. As a convenient means for lifting the front end of the hopper I have shown the plunger it working in the hydraulic cylinder 15, said plunger having a pulley 16 over which passes the lifting cord 17. The front end of this cord is affixed while its rear end is connected to the front portion of the hopper,

The discharge portion 11 comprises essentially the side walls 18 and 19 and the back piece 20. The hopper has its front end 12 closed, but its rear end is open and communicates directly with the discharge portion. The side walls 22 and 23 of the-hopper preferably slope down toward its bottom 24'. the slope of said side portions being ordinarily greater than the angle of repose of the material of the load. The rear portion of the hopper seats inside of the side walls of the discharge portion as shown in Figs. 3 and 4, working inside of the rear portion when the front end of the hopper is raised. As the liftin operation proceeds the rear edges of the si e portions 22 and 23 ward the sides 18 and 19, of the discharge portion. This is by reason of the fact that the hopper is pivoted on the line 13. I have, therefore, illustrated the off-sets 25 between the side walls 22 and 23 of the hopper and the side walls 18 and 19 of the discharge portion, the front portions of these oihsets being closed in any desired manner.

As the front end of the hopper is raised the load contained therein. will slide back and down into the discharge portion. Therefore by simply raising the said front end until the bottom 01"" the hopper reaches the angle of repose of the material, the entire load can be discharged from the hopper. The function of the discharge portion is to receive this material and direct it to one side or the other, or straight down, as desired. I will now describe the particular constructions illustrated for accomplishing these results.

To the lower edges of the sides 18 and l9 of the discharge portion'are hinged the side plates 26 and 27, respectively, so that said plates can swing from the POSlillOIlSSllOWH in Fig. 4 to the position shown at the left hand of Fig. 3. The lower part of the discharge portion includes the front and back plates 28 and 29, respectively, between which the plates 26 and plates 28 and 29 are .provided with the slots 30 and 31 for the accommodation of the locking pins 32 on the lower ends of the plates 26 and 27. These slots are concentric with the axes 33 on which the plates are hinged.

The rods 34 extend across between the plates 28 and 29 underneath the slots 30 and 31; and each of said rods carries a lever 35 at its front end and another similar lever at the back end. Springs 36 connected to the levers 35 at the front ends of the rods tend to swing said levers into the position shown at the right hand side of Fig. 4, so as to maintain. the side plates 26 and 27 in the position occupied by the plate 27 as shown in said figure. Also if one of these side plates be in the lowered position, shown in Figs. 2 and 3, it may be swung upward into the position shown in Fig. 4, snapping past ,the corresponding levers 35 at such time and then being locked in the elevated position. For the purpose of tripping the side plates 26 and 27 I have provided the hand levers 37, which are ivoted to the discharge portion at a suitable point, their rear ends being connected to the levers 35 by means of the links38. Upon depressing the outer end of either of the levers 37 the corresponding side plate will be tripped.

In the lower part of the discharge portion there are pivoted the chute plates 39 and 40, the same being pivoted on the axes ll. These chute plates normally stand in 27 are hinged. The

the position illustrated in Fig. 3 where they line up with the corresponding side plates 26 and 27. For this purpose each of the plates 39 and -10 is provided with a bracket 42 which rests on one of the sills 43 of the chassis. These chute plates 39 and 40 can be swung into the vertical position shown in Fig. 4;.

Between the lower edges of the side plates 26 and 27 there is supported the central plate all. This central. plate normally stands in the horizontal position between the lower edges of the side plates, fillin the gap between the said plates to thereby close in the opening in the discharge portion, and sustaining the load in the wagon. Nevertheless this central plate can be swung down into the position shown in Fig. 3 wherein it alines with the side plate 27 and chute plate 40, or it can be thrown into a similar position in the other direction ali'ning with the The lower edge of each of the side plates is provided with a hooked portion 4:5 throughout its full width. This hooked portion comprises practically a semi-circle.

Each end of the central plate 44. has the rounded or beaded portion 46 which tilts easily in the semi-circular hooked portion 45 of the corresponding side plate, so that the central plate can swing down into alinement with either of the side plates as has been previously explained. Opposite to some portion of the length of each of the beaded portions 46 there is a hook 47 occupying substantially ninety degrees of arc, and adapted to travel outside of the corresponding hooked portion 45. Thus the portion 45 lies between the beaded portion 46 and the hooked portion 47.

In examining Fig. '8 it will 'be apparent that the side plate illustrated therein can swing away from the central plate into the straight down into the dotted line position shown in Fig. 9. It is thus evident that' with this peculiar form of interlocking hinge it is possible for either of the side plates to be dropped down. away from the central plate, or it is possible to permit the central plate to swing down about the lower edge of either side plate as an axis, in which This condition will also remain. if the central plate be allowed to hang iaais latter case the central plate cannot pull away from the side plate after it has swung past a certain position.

The upper edge of each ofthe chute plates 39 and 40 has the hook-portion 48. These hooked portions are so positioned and formed on the chute plates that when the latter stand in their normal positions illustrated in Fig. 3 the lower edge of the central plate will be caught by the one or the other when it is dropped down away from one of the side plates. In this way the lower edge of the central plate will be supported so that the central plate will form a continuation of a side plate and the chute plate corresponding thereto.

When it is desired to bring the plates into the position above described it is only necessary to trip that side plate w ich is on the side of the wagon to which it is desired to discharge the load. Thereupon the side plate will swing down into the position shown in Fig. 3, releasing the adjacent side of the central plate, and permitting said central plate to fall into the position shown in Fig. 3. This will provide a continuous chute for the discharge of the load at the proper side of the wagon.

When it is desired to discharge the load straight down both of the chute plates 39 and 40 may be turned into the position shown in Fig. 4 wherein their upper edges are spread apart as far as possible and then one of the side plates may he tripped to release;,the central plate. When this is done the central plate will be permitted to hang straight do wn from-the other side plate, and the load will be discharged straight down between the chute plates.

It will be observed from an examination of Fig. 1 that the discharge portion is illustrated as depending from the frame or chassis behind the rear wheels &9. Thus the Wagon is of such construction that it can be backed up to a chute or manhole so as to readily discharge the load to any desired point without interference from the frame of the wagon.
